Currency
a.k.a. Money
A country's or region's money, such as the dollar, euro or yen.
In plain English
A country's or region's money, such as the dollar, euro or yen.
A currency is a system of money people agree to use for paying, pricing and saving. Today most are fiat: backed by government decree and trust, not gold.
Every currency has a three-letter code, like USD or EUR. In forex they always trade in pairs, because a currency's price only means something compared with another one.
